The location is great. Right across from train and underground.
Most of the staff is great except one front desk girl. When I told her the WiFi is not working, she blamed it on everything else so she doesn't have to deal with it. At one point, she even told me to go back to my room because it'll work better there.
There's 2 network to log onto. There are times when both doesn't work. It's frustrating if you need it to plan your activities or if you have to do work.

Across the road from the main train station which offers direct train to airport.
Shopping, 10mins walk to the shopping to shopping district. And direct bus to outlet is right outside the hotel.
Convenience wise, best location. But it is not one of the nicer areas in town, though Munich in general is very very safe.
Requested early check in at 7am due to incoming flight, perfectly arranged.
Room facing courtyard should be quite. But the rate I booked is to the road, even side road can be noisy as construction site next door and bars downstairs.
